Abstract:
In order to investigate the plant density and nitrogen level on nitrogen use efficiency components (agronomical, physiological, apparent recovery and nitrogen use efficiency), the amount of nitrogen uptake by plant, yield and yield components of potato (Solanum tuberosum L.) Agria cultivars` tuber, a factorial experiment based on randomized complete block design was conducted in Ardabil, Iran, in 2006 with three replications. Factors were adjusted for the nitrogen level (0, 80, 160 and 200 kg ha-1 net nitrogen) and plant density (5.5, 7.5 and 11 plant m-2). Results showed that with increasing the nitrogen levels and plant densities agronomical nitrogen use efficiency, physiological nitrogen efficiency and nitrogen use efficiency were decreased and apparent recovery nitrogen efficiency was increased. The most nitrogen uptake in plant was observed at the 200 kg ha-1 net nitrogen. The most yield and number of tuber per unit area were gained at the 80 and 160 kg ha-1 net nitrogen. Increasing the plant density resulted in increasing in the tuber yield per unit area and the rate of nitrogen up to the 160 kg ha-1 net nitrogen. So, application of the 80 kg ha-1 net nitrogen and plant density of 11 plant m-2 is recommended to get highest yield with the most nitrogen use efficiency.
